2019-08-02enetc: Add mdio bus driver for the PCIe MDIO endpointClaudiu Manoil6-9/+132
ENETC ports can manage the MDIO bus via local register interface. However there's also a centralized way to manage the MDIO bus, via the MDIO PCIe endpoint device integrated by the same root complex that also integrates the ENETC ports (eth controllers). Depending on board design and use case, centralized access to MDIO may be better than using local ENETC port registers. For instance, on the LS1028A QDS board where MDIO muxing is required. Also, the LS1028A on-chip switch doesn't have a local MDIO register interface. The current patch registers the above PCIe endpoint as a separate MDIO bus and provides a driver for it by re-using the code used for local MDIO access. It also allows the ENETC port PHYs to be managed by this driver if the local "mdio" node is missing from the ENETC port node.

2019-08-02enetc: Clean up makefileClaudiu Manoil1-12/+6
Clean up overcomplicated makefile to make it more maintainable. Basically, there's a set of common objects shared between the PF and VF driver modules. This can be implemented in a simpler way, without conditionals, less repetition, allowing also for easier updates in the future.

2019-08-02enetc: Clean up local mdio bus allocationClaudiu Manoil1-48/+46
What's needed is basically a pointer to the mdio registers. This is one way to store it inside bus->priv allocated space, without upsetting sparse. Reworked accessors to avoid __iomem casting. Used devm_* variant to further clean up the init error / remove paths. Fixes following sparse warning: warning: incorrect type in assignment (different address spaces) expected void *priv got struct enetc_mdio_regs [noderef] <asn:2>*[assigned] regs Fixes: ebfcb23d62ab ("enetc: Add ENETC PF level external MDIO support") Signed-off-by: Claudiu Manoil <claudiu.manoil@nxp.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

2019-05-24enetc: add hardware timestamping supportY.b. Lu6-6/+189
This patch is to add hardware timestamping support for ENETC. On Rx, timestamping is enabled for all frames. On Tx, we only instruct the hardware to timestamp the frames marked accordingly by the stack. Because the RX BD ring dynamic allocation has not been supported and it is too expensive to use extended RX BDs if timestamping is not used, a Kconfig option is used to enable extended RX BDs in order to support hardware timestamping. This option will be removed once RX BD ring dynamic allocation is implemented.

2019-01-24enetc: Add RFS and RSS supportClaudiu Manoil7-3/+554
A ternary match table is used for RFS. If multiple entries in the table match, the entry with the lowest numerical values index is chosen as the matching entry. Entries in the table are identified using an index which takes a value from 0 to PRFSCAPR[NUM_RFS]-1 when accessed by the PSI (PF). Portions of the RFS table can be assigned to each SI by the PSI (PF) driver in PSIaRFSCFGR. Assignments are cumulative, the entries assigned to SIn start after those assigned to SIn-1. The total assignments to all SIs must be equal to or less than the number available to the port as found in PRFSCAPR. For RSS, the Toeplitz hash function used requires two inputs, a 40B random secret key that is supplied through the PRSSKR0-9 registers as well as the relevant pieces of the packet header (n-tuple). The 6 LSB bits of the hash function result will then be used as a pointer to obtain the tag referenced in the 64 entry indirection table. The result will provide a winning group which will be used to help route the received packet.

2019-01-24enetc: Add vf to pf messaging supportClaudiu Manoil7-0/+399
VSIs (VFs) may send a message to the PSI (PF) for general notification or to gain access to hardware resources which requires host inspection. These messages may vary in size and are handled as a partition copy between two memory regions owned by the respective participants. The PSI will respond with fail or success and a 16-bit message code. The patch implements the vf to pf messaging mechanism above and, as the first application making use of this support, it enables the VF to configure its own primary MAC address.

2019-01-24enetc: Introduce basic PF and VF ENETC ethernet driversClaudiu Manoil10-0/+3380
ENETC is a multi-port virtualized Ethernet controller supporting GbE designs and Time-Sensitive Networking (TSN) functionality. ENETC is operating as an SR-IOV multi-PF capable Root Complex Integrated Endpoint (RCIE). As such, it contains multiple physical (PF) and virtual (VF) PCIe functions, discoverable by standard PCI Express. Introduce basic PF and VF ENETC ethernet drivers. The PF has access to the ENETC Port registers and resources and makes the required privileged configurations for the underlying VF devices. Common functionality is controlled through so called System Interface (SI) register blocks, PFs and VFs own a SI each. Though SI register blocks are almost identical, there are a few privileged SI level controls that are accessible only to PFs, and so the distinction is made between PF SIs (PSI) and VF SIs (VSI). As such, the bulk of the code, including datapath processing, basic h/w offload support and generic pci related configuration, is shared between the 2 drivers and is factored out in common source files (i.e. enetc.c). Major functionalities included (for both drivers): MSI-X support for Rx and Tx processing, assignment of Rx/Tx BD ring pairs to MSI-X entries, multi-queue support, Rx S/G (Rx frame fragmentation) and jumbo frame (up to 9600B) support, Rx paged allocation and reuse, Tx S/G support (NETIF_F_SG), Rx and Tx checksum offload, PF MAC filtering and initial control ring support, VLAN extraction/ insertion, PF Rx VLAN CTAG filtering, VF mac address config support, VF VLAN isolation support, etc. Signed-off-by: Claudiu Manoil <claudiu.manoil@nxp.com> Signed-off-by: David S.
